Gridview e.OldValues and e.NewValues are nothing

[Pulkit Sharma]

Hi,

I am using a gridview control in asp.net 2.0 and creating some dynamic
template fields in it. Whenever I am trying to get the e.NewValues in the
row_updating event , it is always nothing,

Is this a know issue? If there is a work around please let me know.

Protected Sub gridSystemLookUpValues_RowUpdating(ByVal sender As Object,
ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles
gridSystemLookUpValues.RowUpdating
' e.OldValues and e.NewValues is always nothing here

End Sub


Regards

Pulkit

Hi Pulkit,

Since you didn't posted your complete code listing, I'm not sure if this
the same scenario as following thread:

#GridView, DataSource, RowUpdating, e.OldValues and e.NewValues collections

Would you please check if this is the same issue? Please feel free to tell
me more about your code if that thread doesn't help. Thanks.

If I am understanding you correctly, the reason e.NewValues and e.OldValues are not populated is that you are dynamically populating the gridview. The e parameter relies on a design time datasource to populate these values.

In order to make this work, you will have to programmatically grab the values from the edit and create an update.

Hi geneB,

I am actually trying to update the gridview at run time and hence my
GridViewEditEventArgs e goes blank as soon as I hit the update button. I am
able to trap the oldvalues before i start to edit using the static variable
concept but i cannot seem to find out the way to get the new values in the
gridview. Can you please guide me? Any help would be highly appreciated?

cheers!
